Former Wales flanker Kingsley Jones was also appointed as forwards coach in June while six new faces have been added to a playing staff boosted by contract extensions for Toby Faletau and new captain Andrew Coombs.
By Edwards' own admission last season did not go according to plan, but he believes the new arrivals have provided just the jolt needed ahead of the new RaboDirect PRO12 campaign.
"Pre-season's been good, we've had a lot of changes in the coaching teams and within the squad of players - and with change it creates a lot of optimism," said Edwards, who joined the Dragons in April 2011.
"You've got to be honest and reflect on how the season has been, in terms of our expectations it didn't go as well as we wanted it to.
"Inevitably change needs to happen, I firmly believe the changes that have taken place are for the greater good and are a positive and I think everybody sees that.
"You have to address things with a squad of players, they weren't strong enough. Therefore we have had to recruit and make those positions stronger so a competitive squad can be reflected on the field.
"Behind the scenes from a coaching point of view, we've got a new director of rugby Lyn Jones and Kingsley coaching the forwards, both very experienced men who are used to dealing with the pressures of the game and coming from a different competition gives a new perspective."
And though Edwards is relishing the prospect of a new-and-improved Dragons, he has also issued caution as the squad's overhaul - complemented by young and exciting talent already on the books - takes time to click.
"We're taking it week by week, it's a new squad and new coaches and were going to find a lot of things out about each other as time goes on," added Edwards. "I think it's stimulating and hopefully the journey we go on will be positive and enjoyable too.
"We have a number of young players, in the forwards with Ieuan Jones and Phil Price, then we have Jonathan Evans at scrum-half, centre Jack Dixon, fullback Hallam Amos - these guys have the international potential and that's why we believe we have a bright future."
